    Description

      Epic Goal

      • Add Gateway API via Istio Gateway implementation as Tech Enhanced Dev Preview in 4.13 (proposed)

      Problem: ** As an administrator, I would like to securely expose cluster resources to remote clients and services while providing a self-service experience to application developers. 

      Enhanced Dev Preview:  A feature is implemented as Enhanced Dev Preview so that developers can issue an update to the Dev Preview MVP and:

      • can still change APIs that are clearly indicated as tech preview, without following a deprecating or backwards compatibility process.
      • are not required to fix bugs customers uncover in your EDP feature.
      • do not have to provide an upgrade path from a customer using your EDP feature to the GA version of your feature.
      • must still support upgrading the cluster and your component, but it’s ok if the EDP feature doesn’t work after the upgrade.
      • still need to provide docs (which should make it clear the feature is tech preview)
      • still need to provide education to CEE about the feature
      • must also follow Red Hat's support policy for dev preview

      From https://github.com/openshift/enhancements/blob/master/guidelines/techpreview.md

      Why is this important?

      • Reduces the burden on Red Hat developers to maintain IngressController and Route custom resources
      • Brings OpenShift ingress configuration more in line with standard Kubernetes APIs
      • Demonstrates Red Hat’s leadership in the Kubernetes community.

      Acceptance Criteria (draft)

      • Gateway API and Istio Gateway are in an acceptable standing for Tech E.D. Preview
      • Istio Gateway installation without sidecars enabled
      • Decision completed on whether we use a single control plane (shared between OSSM and Network Edge functionality), or multiple control planes (separate CPs for OSSM and Network Edge functionality)
      • * Decision completed on changes needed to accommodate HyperShift architecture - in OSSM and elsewhere
        -
      • Decision completed on whether a new operator is required, especially for upgrade and status reports
      • Decision completed on whether Ingress->Gateway (or Route->Gateway) translation is needed
      • Enhancement Proposals, Migration details, Tech Enablement, and other input for QA and Docs
      • API server integration, Installation, CI, E2E tests, Upgrade details, Telemetry

      Dependencies (internal and external)

      1. OSSM release schedule aligned with OpenShift's cadence, or workaround designed
